As further examples of dyestuffs coming into consideration for the present process, the acid esters of the following dyestufis may be named: (l) 2,4-dinitro-2'-(5-hydroxyethyl sulfone)-4'- phenylamino-diphenylamine.

(2) 4-(5-hydroxyethyl sulfone-4'-(2",4" dini- 4 ethyl sulfone)-benzthiazo1e, by means of hypochlorite.

The following process may also be used: The fibers are impregnated in a neutral or acid bath with a compound capable of coupling, which contains one or more groupings sulfone) -2,2-thiodoes not occupy the coupling position.

For example, the salts of the 5-hydroxyethyl sulfone ester of a 2,3 -hydroxynaphthoicacid arylide can be taken up by wool in an acid or neutral solution, then the material may be treated with a weak alkali, such as sodium acetate or soap, and the coupling with a diazonium compound may be carried out subsequently.

By the present invention it is also possible to improve the fastness properties of dyestuffs containing groups, such as amino or hydroxyl groups,

capable of reacting with vinyl sulfone groups by combining such dyestufis with the compounds,

containing the above grouping and after-treating them.

The process of the present invention is, how- ?Ver, not limited to the production of dyeings.

The leather may be fat-liquored in the usual manner in the same bath with 2 to 3 per cent. of sulfonated oil, such as castor oil or a fish oil. The fat-liquored leather is rinsed shortly and further treated as usual. The percentages are calculated upon the shaved weight. A brown leather dyeing is obtained which has very good covering properties and a good fastness to wet processing.

We claim:

1. Process for fixing water-soluble organic compounds in the form of water-insoluble derivatives thereof on materials of fibrous structure which comprises applying to the material a water-soluble compound corresponding in the free form to the general formula wherein A is an insoluble radical of an organic compound, R, R1 and R2 are members of the group consisting of hydrogen and alkyl and n is one of the numbers ranging from 1 to 3, and subjecting the treated material, as an essential part of said fixing operation, to the action of an agent of alkaline reaction to form the waterinsoluble derivative of the compound.

2. Process for fixing water-soluble organic compounds in the form of water-insoluble derivatives thereof on materials of fibrous structure as claimed in claim 1 wherein the said agent has a weakly alkaline reaction.

22 3. Process for fixing water-soluble organic compounds in the form of water-insoluble derivatives thereofcn materials of fibrous structure which comprises applying to the material a water-soluble compound corresponding in the free form to the general formula A(SO2-CH2-CHz-OSO3H) 1.

wherein A is an insoluble radical of an organic compound, n is one of the numbers ranging from 1 to 3, and subjecting the treated material, as an essential part of said fixing operation, to the action of an agent of weakly alkaline reaction to form the water-insoluble derivative of the compound.

4. Process for prcducingfast dyeings of water-insoluble derivatives of dyestuffs on a textile fiber which comprises applying to the fiber a water-soluble compound corresponding in the free form to the general formula wherein A is an insoluble radical of a dyestuff compound, 1!. is one of the numbers ranging from 1 to 3, and subjecting the treated material, as an essential part of said dyeing operation, to the action of an agent of weakly alkaline reaction to form the water-insoluble derivative of the dyestufi compound.

5. Process for producing fast dyeings of watar-insoluble derivatives of azo-dyestufis on a textile fiber which comprises applying to the fiber a water-soluble compound corresponding in the free form to the general formula wherein A is an insoluble radical of an azo-dyestuff, n is one of the numbers ranging from 1 to 3, and subjecting the treated material, as an essential part of said dyeing operation, to the action of an agent of weakly alkaline reaction to form the water-insoluble derivative of the 3.20- dyestufl.
